Обсуждение: About table column names.

Hi the list !
As far as I know, column names for a table can't contain any space,
tabs, and other sort of "exotic" characters. Is there a way to add a
description of a table column anywhere in postgres tables, or does it
have to be handled manually by creating a custum table handling this
kind of datas ? Thanks by advance for any suggestion.

In fact, I know you can have at least spaces in your column names, like this:

mark=> create table t ("column one" text);
CREATE

Just put quotes around them.

I'm interested in this, too. It seems more useful than having them in a
SQL file...which can sometimes get out of synch with the database. :)

COMMENT ON COLUMN table.col IS 'whatever';
